GhidrAI

GhidrAI is a Ghidra extension which uses Alibaba Cloud LLM services explain what a function does, and to automatically rename its variables. Most importantly, these services are free :)

Requirements

The GhidrAI is verified on Ghidra 10.4. Note: Ghidra 10.4 requires JDK 17 64-bit.

Building GhidrAI

Use the following steps to build GhidrAI for your environment:

• Install Ghidra using the documentation here
• Install Gradle from here
• Download the latest GhidrAI source release from here
• Run the following command from the GhidrAI source directory:
  • Note: you may optionally set an environment variable named GHIDRA_INSTALL_DIR instead of specifying -PGHIDRA_INSTALL_DIR

$ gradle -PGHIDRA_INSTALL_DIR=<absolute path to Ghidra install>

This command builds GhidrAI. If successful, you will find a new directory in your GhidrAI source directory named dist containing your GhidrAI extension (.zip). Please open a new issue if you experience any issues. (Please provide the log file at ~/.ghidra/.ghidra_${VERSION}/application.log.)

Installing GhidrAI

Use the following steps to install your GhidrAI extension in Ghidra:

• Note: For Alibaba Cloud DashScope, you must use the DASHSCOPE_API_KEY environment variable.
• Start Ghidra
• Navigate to File > Install Extensions...
• Click the green + button
• Navigate to your GhidrAI extension built earlier (.zip)
• Click Ok
• Restart Ghidra

OR

You can extract your GhidrAI extension (.zip) directly to <absolute path to Ghidra install>\Ghidra\Extensions and Ghidra will prompt you to configure GhidrAI the next time it is started.

Using GhidrAI

Select the function and right click the mouse, you can find the option in the menu.

Click Tools > GhidrAI, and you can find the configruation dialog. For more detailed information, refer data/README.md.

GhidrAI also provides an automatic analyzer, you can find it in Analysis > Auto Analyze ... or Analysis > One Shot.

Acknowledgment

This project refers to the Ghidrathon plugin, which provides out-of-box Python3 integrations for Ghidra. My original idea is to utilize Ghidrathon to run LLMs locally. But directly requesting services such as Alibaba Cloud DashScope saves my time.

And apparently the idea is from Gepetto.
